ROLLER FOR PARLOR-SKAIES.

SPECIFICATION forming part of Letters Patent No. 279,406, dated June 12, 1883.

' ApplicationfiledAprilli),1883. (No model.)

To all whom it may concern:

Be it known. that I, EBEN B. MANSFIELD, of Malden, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Rollers for Parlor- Skates, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claims.

This invention relates to the rollers which are pivotally arranged beneath that class of skates known as parlor-skates; and the invention consists in the construction and combination of the divers devices embodied therein, as hereinafter more particularly and fully set forth and claimed. The rollers employed in parlor-skates require, in order to perform satisfactory service, certain qualities or characteristics, among which the following may be enumerated: first, noiselessness, or as near an approach thereto as can be attained without sacrificing other essential qualities; second, the least practicable tendency to abrade and wear out the floor; third, durability, both as regards wear upon the axis or pivot of the roll and upon the outer face or periphery of the rolls; fourth, just the requisite adhesion or grip upon the floor to give the skaterabase for the exertion of his strength; fifth, a roll that is practically a true circle at all times, but which is slightly yielding, in order that it may act as a cushion between the operator and the floor. From long-continued experiments I have demonstrated that leather gives the most satisfactory grip or contact with the floor. It does not adhere with the objectionable tenacity of rubber, nor does it slip as easily as wood, and it does not injure the floor like wood; nor does it compress or fiat-ten like rubber, thereby giving the effect of always rolling uphill, and is practically noiseless and causes a minimum amount of injury to the floor. On the other hand, wood of proper quality-such. as I box-wood is elastic and durable, and when combined with leather, as will be described, a roller is produced that in various respects combines the better qualities of both.

In the accompanying drawings, Figure 1 is aside elevation of a roller constructed as shown in Figs. 3, 4, and embodying my invention.

Fig. 2 is a side elevation of a roller constructed as shown in Fig. 5, and embodying my invention. Fig. 3 is a longitudinal section of a roller formed with a central disk of wood and a disk of leather-upon each side thereof, said parts being secured by metal checks or disks held in place by a metal sleeve whose ends are enlarged and riveted in said cheeks. Fig. 4 shows a roll like Fig. 3, except that a sleeve of the wood disk extends through each of the leather disks. Fig. 5 shows a roll like Fig. 4, except that the axial metal tube is not employed, and the metal disks are secured in place by rivets, which are arranged near the periphery, as shown in Figs. 2 and 5, and a sleeve-like projection of the central wood disk extends through the leather and metal disks and receives the pivot on which the roll revolves.

. In said views, a represents a central disk of wood, and b b are disks of leather glued or cemented firmly to the disk 0. Upon each outer face of the leather disks I arrange themetal disks 0, which are preferablyformed of sheetsteel, and, before being secured in place by the central metallic sleeve, (1, as shown in Figs. 1, 3, 4, are slightly concaved upon the face next theleather, in order that the compressive force exerted by said sleeve, when its ends are expanded as a tubular rivet, may cause said disks,-at their peripheries, to more firmly sup .port the leather and prevent its lateral displacement from the wood.

In Figs. 4 and 5 sleeve-like projections e of disk 0. extend through the leather disk, as shown, and in said Fig. 5 said projections or sleeves also extend through the metal disks 0, in which latter case said last-named disks are securedin place by rivets f, which pass entirely through the roll, as shown and when said disks are so confined their concave side is placed outward, as the rivets secure their peripheries closely against the leather. The pro; jections e possess the advantage of fin'nishing afirm seat for tube (1, and also tend to support and secure the leather disks in proper position relatively to disk (1, even though the connecting glue or cement should become impaired.

I do not herein broadly claim the employ ment of leather in skate-rollers, nor do I claim the method of Securing the metallic disks in position by a central sleeve or rivets my in- 2. In a skate-r011 embodying the wood disk vention consisting in the combination of wood a and leather disksb I), asleeve-like' projection IO and leather in such rolls and in the methods 6, formed upon disks (0 and extending through of carrying out the same; hence the leather disks, substantially as specified. 5 I claim as my invention EBEN B.
